Origin: The ancestors of Cylindricus lived in Lake Tanganyika. But now they live in aquariums all over the world.
Maximum Size: In aquariums, they can grow to be about 5" long, including their tails, which is a nice size for aquariums with at least 80-gallons of water.
Behaviors: Cylindricus are usually very aggressive and can be even more aggressive to each other, and then when getting ready to lay eggs and protecting their babies.
Compatibility: Some recommended tank mates include other Tanganyika Cichlids but not Cichlids from Lake Malawi nor from Lake Victoria. Cylindricus are often kept with Synodontis Catfish, but Synodontis will eat baby fish.

Temperature: Cylindricus live best from about 75 to 80-degrees F. with 78 being perhaps ideal.

Feeding: Premium Fish Food Pellets is a good food for Cichlids to eat.
It would be best to feed them small pellets when young, then gradually increase the size as they grow bigger.
In their natural habitat Cylindricus eat small crustaceans and invertebrates, and Cylindricus seems to be a very picky eater that may require small live or frozen food.

Water Conditions: These fish can adapt to most types of water, and so as usual it's best not to try to change the pH or alkalinity.

Aquarium Size: Cylindricus will eventually need to live in an aquarium with at least 40-gallons of water.
Each Cichlid will need at least 3-gallons of water.
Decor: Cylindricus do not need gravel, and a layer of gravel more than 1/4" thick will usually fill with bits of uneaten food that will contaminate the water.

Live plants are beautiful and improve the water quality, but most aquariums with Cylindricus do not have live plants.
Aquarium Filter: Bio-Wheel Filters are highly recommended.
Most 40-gallon aquariums need a Penguin 350B Filter, and this is sort of the minimum set up for Cylindricus.
Better is a 80, 100, or 120-gallon aquarium with as many Penguin 350B Filters as will fit across the back.

The addition of Lava Rocks will keep nitrates in the ideal range.

Life Span: Cylindricus can live for several years.
Keep the water conditions excellent and feed them premium foods, and they'll most likely breed and produce the next generation of fish for your aquarium.
Gender: It's usually very difficult to distinguish males from females. Breeding: Cylindricus lay eggs in a cave and carefully protect their eggs and then their babies.

Popularity: These Cichlids are rare and have not yet had a chance to become popular aquarium fish.
Names: The scientific name for the Cylindricus is Neolamprologus cylindricus.
Variations: This species occurs a wide region of Lake Tanganyika and there are several variations and hybrids with other Neolamprologus species.
This variation from Gombe is perhaps the nicest variation.
